WINDOW REGULATOR.

Applicationfiled February 21, 1921. SerialNo. 446,893.

My invention relates to improvements in window regulators and is more particularly directed to a n'ieans for regulating windows in the doors of the bodies of automobiles.

One object of my invention is to provide a device of this character by which a window in the body of an automobilemay be readily raised or lowered.

Another object of thisinvcntion is to provide a device by which the position of a window in anautomobile body may be regulated,

with little effort.

A further ohgect of the inventlon is to provide a device of the characterdescribed wherein an operating means is secured to the window of an automobile body andby' which means the operator of the car may progressively elevate or lower the window vide a device of the character describcd'in which a rod provided with an operating lever and attached to a portion of the window in an automobile body will guide the window 'into'a number of positions, when the said rod is operated.

- Another object of the invention is to provide a simple supporting frame for the window. glass in an automobile body having means by which the window can be support ed and fastened in a predetermined position. Other objects, of this invention relate to economies of manufacture and details of construction which will hereinafter appear in the detailed description to follow.

The objects of the invention are acconr plished in one instance by the devices and means described in the following specificati on, but it is evident that the same may vary widely without departing from the scope of the invention, as pointed out in the appended claims.

A structure constituting one embodiment of the invention, which maybe the preferred, is illustrate-d inthe accompanying drawing, forming a part hereof in which:

Figure I is a front elevation of the door of I Figure III is a view in. detail of the finger piece connected with the upper end of the operating rod.

Figure IV is a transverse sectional view of Figure II along the line IV-IV of Figure II.

The device comprises three units, the door fran'iewhich carries the window and its operating parts, secondly, the window glass and its frame includingthe operating parts connected wth the window, and third, the counterbalance which overcomes the weight of the glass so that the same may be more readily raised or lowered.

p The door frame lcomprises side members 2 and 3, joined by the upper and lower cross pieces 4 and 5 respectively, and braced by'an intermediate member 6, the lower end of the door being further braced by a foot board 7. Vertical guides for the window 8 are formed in the side pieces 2'and 3. Each guide comprises an outer stop portion'9 which is made integral with the side frame members 2 and 3 of the door frame, a felt lining 10 in which the glass 8 slides, and an inner stop member.

The inner stop members 11 and 12 are identical in configuration, but while the member 11 is preferably made of solid material, the member 12, having a double function which will be presently described, is made of sheet metal and bent to conform to the shape of the inner stop member 11. d

On the bottom of channel frame 13 to which is secured an operating rod 14L. The rod is threaded at 15 upon which a nut 16 is screwed. A split ring 17 v and a lock nut 18 securely fastens the free end of a connecting member 19 imposition on v the rod 14. The connecting member 19 is provided with two angular bent portions and connected at its other end by a screw 20 to the channel frame 13 which is attached to the the window is secured a I The member 12 not only forms part of the I guide way for the glass 8, butacts as a guide and keeper for the operating rod 14 of the glass, and as such comprises a base member 21, a stop member 22 which is at right angles to the base member and forming the inner part of the guideway for the glass, and a curved of the door and comm the pivot point of the it lowered or raised It the top member 28, the free end of which lies adacent the free end of the stop member 22,

pressed finger piece 25 of the rod 14. The freeend of the top member is arovi ded with a series of notches 26 to receive the finger piece 25 to position the window in any desired position. I

- The member 12 is secured to the side frame members b i any suitable means such as screws '27 passing through the top and base members and 28 respectively. 7 V V lhe end of the operating rod l l is bii urcated at 28in receive one end of a spring" 29 mounted inthe sleeve 30. the other end being secnred in a in sleeve 30. The lot in which i pied to prevent o..:rillatory movement The counterbalance oted interme its and pro ectinq downwai dl andS'T joined by a thir linl: 3S hasaseries of oi which'the free end of asown 5H is en gaged. 'The other end of the spring s0 .is' if it stoned to the lower cross piece by means of an eye bolt 41. A pulley 42011 the free end of the lcvergaengages the channel frame. 7

' The operation of the device is as follows: 7 7 e being located in one of T he finger plec the notches 26 oi he guide member 12, is removed by the operatorand he rod 14 may be i a od 14 is lowered, the window 8 being connected with the rod is carried downwardly together with the free end of thelever bvreason of its engagement with the channel frame; 13 of the window through the medium of the pulley 42 on the end of the lever 35,. Thusthe depending link 38 is shifted to the left. carrying with it the upper end of the '40 which is slightpositions withoutincreasing or diminishing the pull on the spr ng in the 'dr" rent positions of the window. The finger piece being removedfrom one of the notches will allow the window to be raised or lowered step by step by the operator. When the finger piece siderabledetail an embodi of my inven t on,;it is to be understoodthat this showing 0 check the and'description is illustrative only, and for the purpose of rendering my invention more and forming therewith a slot 2% for a spring clear, but that I do not regard the same as limitcdto the, details of construction illustrated or describedyor any of them. except 7o insofar as I have included such limitations within the terms of the following claims, in which it is my intention to claim all novelties inherent in myinvention, broadly, as well as spe ifically.
